Dual-Frequency 125 kHz + 13.56 MHz RFID Module, UART/USB: overview
The XM-200 is a dual-frequency RFID module for OEMs who want one board to read legacy 125 kHz proximity credentials and 13.56 MHz smart cards. On the low-frequency side it handles EM4100, EM4102, EM4200, EM4305 and EM4450 transponders plus HID Prox-compatible cards. On the high-frequency side it reads MIFARE Classic, DESFire EV1/EV2, Ultralight and Ultralight C, FeliCa, ICODE, CEPAS, CPU cards and NFC Forum Type 1–5 tags. That makes it a practical core for door readers, turnstiles, elevator panels and EV chargers on sites moving from prox to DESFire.
The board measures 30 × 16 × 9.2 mm and weighs about 1.8 g. Both antennas are external, so the 125 kHz coil and the 13.56 MHz loop can follow the shape of your enclosure, keypad or display instead of the other way around. Protocol coverage includes ISO/IEC 14443A/B, ISO/IEC 15693, ISO/IEC 18092 and FeliCa, the rated range is –40 to +85 °C, and a configuration tool handles settings and serial-port firmware updates.
Integration notes
A 6-pin, 2.0 mm pitch header carries 5 V DC, ground, a 3.3 V TTL UART at 115200 bps and USB full-speed (12 Mbps) data lines, so the same part can sit on a microcontroller UART or connect straight to a Windows, Linux, Android or macOS host. The antennas plug into a 4-pin, 1.25 mm connector: plan for a 490 µH ±10 µH coil at 125 kHz and a 50 Ω antenna at 13.56 MHz. Current is ≤ 180 mA with the RF field on and ≤ 30 mA with it off. CE, FCC, RoHS and Japan Radio Law approvals are listed for the module; your finished device still needs its own compliance assessment.

XM-200 FAQ
Can one module read both our old prox cards and new DESFire cards?
Yes. It reads 125 kHz EM and HID Prox-compatible credentials and 13.56 MHz MIFARE Classic and DESFire EV1/EV2 cards through two external antennas, so one reader can serve a mixed card population.
Should I use the UART or the USB interface?
Both are on the 6-pin header. Use the 3.3 V TTL UART at 115200 bps with a microcontroller, or the USB lines (12 Mbps) for a direct link to a Windows, Linux, Android or macOS host.
What antennas does the module need?
Two external antennas on the 4-pin, 1.25 mm connector: a 125 kHz coil of 490 µH ±10 µH and a 50 Ω antenna for 13.56 MHz. Their shape can be adapted to your enclosure.
What read range can I expect?
No fixed range is specified because it depends on the antennas you design in and on the credential. Send us your antenna or enclosure drawing and we will test samples with your cards.
Can the firmware be updated in the field?
Yes. Firmware is upgraded over the serial port using the configuration tool supplied for the module.
